Google Pay™

Google Pay™

The Google Pay API enables fast, simple checkout on the website, and gives the merchant convenient access to hundreds of millions of cards saved to Google Accounts worldwide.

General Information

Qenta uses the credit card data from the Google Pay checkout to initate a transaction with the merchant’s credit card acquirer activated on the customerID. This also means that the payout happens via the appropriately activated/used credit card acquirer. Some credit card acquirer cannot handle Google Pay. Please get in touch with our sales department for further information.

Example: If AMEX is not activated on the CustomerID, an AMEX credit card is also not selectable during Google Pay checkout

Supported Acquirer

The chosen credit card acquirer must support Google Pay.

Acquirers supporting Google Pay:

  • Card Complete

  • SIX AT (Paylife)

  • Hobex

  • American Express


Qenta handles the entire payment process in the background, a seperate registration for Google Pay is not required!


Google Pay API payment method can be initialized if the merchant sends GOOGLEPAY for parameter paymentType.

3D Secure/Recurring
